Can auto darkening welding helmets capsule be restored..
After some years decided to practice Aluminium Tig welding today.
I have a Parweld helmet that is as new I hardly used as not fine enough for low amp welding that I was doing on my flash steam stainless generators.
Also a SWP that was great for welding with a few amps.
The auto capsules are not working any chance they can be made working again.
Did get an odd darkening but very rare..
They both are hardly used I know there are some cheap solar ones on Ebay.
If I can repair them easily would prefer to do that..

As Andrew said, probably the batteries, and most of these cheap helmets don't allow easy battery replacement - I had two such and did cut open the module - there were two lithium cells, in series, with the center tap also connected so seems like it used a split supply. Did that about 7 months ago, and this weekend the helmet is playing up again..
This helmet also has small PV panels, but as I don't do much welding, the helmet sits in a box so no sunlight and no welding UV and it appears the quiescent current is not insignificant.
I again replaced the batteries, but with two D Cells, duct taped to the top of the helmet..

If your local store has any left, Lidl had some on offer recently, which may work out easier.
I've not tried them, so I don't know the quality

Have jumped the gun the parweld has mainly been in its box for ten years its manual says the built in battery will only last 6 years.
After being in the light all day its working again.
The 10 year old SWP has started working again after leaving near when I practiced a few hours ally Tig welding.

The SIP basic £40 one has a grinding option which switches the battery off. The battery is a CR3032 car key fob type. If it sees welding flash it still darkens.

It will be the batteries. I had 2 Chinese that went the same way. The first had a draw for an AAA cell but the cell had been in too long and I had to clean up the terminals. The second had a coin cell battery inside which I replaced and neither helmet is now going to land fill.
During the helmet recovery process I discovered in addition to the electronic auto shut off, my darkening control knob had a switch on the end and when off, nothing drains the battery. I now remember to turn it to the off position.

If they are the type with the small solar cells on the front, I believe they can sometimes be 'kick started' by leaving them in the sun for a few hours.
I have one of the cheap supermarket ones (Aldi, I think) with 2 arc sensors and while it is/was fine for stick welding, it wouldn't reliably stay dark with low-ish amp TIG. (A relatively inexpensive 'Tacklife' branded one with 4 arc sensors did work OK, however.)

Otherwise known as grinding mode
